There is next to zero need for more than a single speed unless top-end speed is required. That is why not a single EV motorcycle that I know of has more than one gear, and almost no EV cars (except for the Porsche Taycan and I think one of the Lucid models) has multiple gears either. Everything else is fine with a single speed, but they tend to quickly lose power above 100 MPH or so (which I think most people think is perfectly fine).
